Detect Webpage in Facebook Messenger In-app Browser

Question

I'm using npm package like Bowser to detect the Browser that I'm using when I'm opening a link. but When I try to open the link in my messenger. It still says that I'm using Chrome, but I'm on Facebook In-app Browser.

Is there any package to detect if using Facebook In-app Browser

Answer 1

you can just create a helper function to do so:

const isFacebookInAppBrowser = () => /FB_IAB/.test(navigator.userAgent) ||
  /FBAN/.test(navigator.userAgent) ||
  /FBAV/.test(navigator.userAgent);

This works for facebook in app but I am not sure for messenger. I didn't even know that it had a browser.
